The Cummins ISX12 diesel engine is a powerhouse, boasting up to 425 horsepower. This significant amount of power makes this an ideal engine for all heavy duty trucking jobs, from dump trucks to municipal uses.
To build on the success of the ISX12, Cummins refined the engine’s technology to deliver better fuel economy while meeting 2014 U.S. Environmental Protection Agency (EPA) greenhouse gas (GHG) emissions standards — and U.S. Department of Transportation (DOT) fuel efficiency standards — a full year ahead of schedule.
A reduction in parasitic losses with a higher efficiency water pump and fuel pump, optimized combustion and fewer active after-treatment regenerations add up to better fuel economy. Lowering fuel use results in less carbon dioxide (CO2) emissions (the main GHG being regulated), so achieving better fuel economy actually meets both standards.
Cummins’ proven On-Board Diagnostics system has been used in thousands of on-road vehicles since 2007. This system continuously monitors performance of the emissions system, providing alerts via a Malfunction Indicator Lamp (MIL) on the instrument panel. The MIL illuminates when it detects a malfunction related to the emissions control system, alerting the operator that the engine needs troubleshooting and possible repair.
Built to last longer maintenance cycles, the ISX12 saves on costs of ownership with oil change cycles up to 15,000 to 35,000 miles.
The Cummins ISX12 is available in the flagship semi truck, the Freightliner Cascadia.
